Abstract Scope |
Heat treatment is widely used to improve the properties of conventional manufactured steel parts. The response of additively manufactured steel parts to heat treatment may be different from conventionally manufactured steel parts. An understanding of heat treatment processes for additively manufactured steel parts is necessary to develop the heat treatment process parameters. In the present work 20MnCr5 steel is selected to investigate the carburization of additively manufactured parts. These parts were fabricated by selective laser melting. The objective of this project is to determine the carburization performance of additively manufactured steel parts. The results for the AM parts in terms of carbon concentration and microhardness profiles are compared with the results for the wrought steel. The mechanical testings including tensile and impact toughness testing are also conducted to compare the mechanical properties at the core of simultaneously carburized AM and wrought parts. |
